Andamans in August - How bad is the rain?

Am planning a trip to andamans in mid- to late- august 2009, after I get married in Darjeeling. Not quite a honeymoon, but want to get away for a few days. Some of my family who will be coming to india for the wedding are also planning a few days near the sea after the wedding.

How bad is the rain in august? I know the south west monsoons will still be there, but as it's nearing the end of the season, will the rain be intermittent?

Any help gratefully appreciated.

Thanks

Emma
